Ok I need to do a single bed quilt for a 4 1/2 year old boy that I don't know. I am a confident quilter with quite a bit of experience. What I don't have any experience is what would be suitable for a boy that age. I will probably use a simple pattern like disappearing 9 patch as the quilt will need to be finished relativity quickly. The mothers house has been described as quite modern. Looking for suggestions folks.

My son is 3 & I did a western themed rag quilt that was easy (King of the Ranch by Moda). I also have a plus pattern of nautical fabrics that is in process for him - also easy. And if you're looking for modern, there are a couple cute ideas in "Stop. Go. Quilt. Sew!" by Angela Yosten that are in my son's future. They are transportation signs (stop signs, no parking, etc) made out of scraps:

I think with boys, the bigger trick is finding "boy appropriate" fabric - there are so many girly fabrics out there. Blue is always a safe bet. I like grays & orange too - we're going to paint my son's room that scheme. And cammo is very boy appropriate. It's a good age - they're not yet super picky, but just out of juveniles. Nature (like the forest, bugs, etc) and dinosaurs are probably a safe bet.
